2 cups rolled oats
1/2 cup almond flour
1/2 teaspoon baking powder
1/4 teaspoon salt
1 teaspoon cinnamon
1/4 cup honey or maple syrup
1/4 cup almond butter (or peanut butter)
1/2 cup unsweetened applesauce
1 teaspoon vanilla extract
1 large egg
1 cup fresh blueberries
Directions
Preheat the oven to 350°F (175°C) and line a 9×9-inch baking dish with parchment paper or lightly grease it.
In a large bowl, combine the rolled oats, almond flour, baking powder, salt, and cinnamon.
In a separate bowl, whisk together the honey (or maple syrup), almond butter, applesauce, vanilla extract, and egg until smooth and well combined.
Pour the wet ingredients into the dry ingredients and stir until fully incorporated.
Gently fold in the fresh blueberries, being careful not to crush them.
Transfer the mixture into the prepared baking dish and spread it evenly.
Bake for 30–35 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean.
Allow the bars to cool completely before slicing into squares.

Variations
For a vegan version, replace the egg with a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water).
Swap blueberries for raspberries, chopped strawberries, or mixed berries for a different flavor profile.
Add chopped nuts such as walnuts or pecans for extra crunch.
Stir in dark chocolate chips for a sweeter twist.
Use peanut butter instead of almond butter for a richer, nuttier taste.
For extra texture, add a tablespoon of chia seeds or flaxseeds to the batter.
Storage/Reheating
Store the bars in an airtight container at room temperature for up to 2 days.
For longer storage, refrigerate them for up to 5 days. Make sure they are completely cooled before storing to prevent excess moisture buildup.
These bars also freeze well. Wrap individual squares tightly and freeze for up to 3 months. Thaw overnight in the refrigerator or at room temperature for a few hours.
To reheat, warm a bar in the microwave for about 15–20 seconds if you prefer it slightly warm.
